At this time, the best method for getting from Revit to VRML is to transfer the model through a VIZ (or 3D Studio Max). The software needed is Autodesk VIZ (or 3DS Max), Revit Architecture and a VRML viewer (we use BS Contact Stereo in the display lab).
The process is:
Create a model in Revit and then export the model to VIZ using instructions in the following tutorial
File - Import - File Type - AutoCAD Drawing and then select the file name. Then select the Import Options - Default and then click ...
It is recommended that any additional materials and textures be added to the model at this stage for presentation quality renderings, or if they did not transfer properly from Revit.
Due to material mapping issues with all model built in VIZ, it is recommended that a "UVW mapping modifier" be applied to each component in the model. Tiling settings may be set when a material is defined but in the material editor it is a global setting.**
Create a navigable model through VRML export
File -Export - Save as Type - VRML(*.wrl) and then click Save
#Texture maps are not referenced properly during the export process outlined in the previous step. The default Bitmap URL prefix in the VRML97 Exporter dialog ...\maps will need to be replaced manually to get the textures in the VRML environment. This can be done using VRMLPad but if it is unavailable the following editing process can be done using Notepad as well. The process below outlines the steps for the second scenario.
##Open exported *.wrl file in Notepad.
##Find all instances of
".\maps\(texture name.jpg)"
##Edit > Replace
##Copy existing URL name into first entry box and in the second entry box, type in the correct URL path.
##Repeat process for multiple materials.
This process is easier in VRMLPad as it organizes the data in a much more user friendly manner.
